Medium sized separation plant

Medium sized air separation plant is a set of air separation unit which extracts oxygen and nitrogen from the air at the same time, which is widely used in many industries. The medium-sized air separation unit can be divided into internal compression process air separation unit and external compression process air separation unit. The internal compression process air separation unit is that the liquid oxygen pump pressurizes the liquid oxygen to a certain pressure and vaporizes it out of the cold box for users' use; the external compression air separation unit is that the micro positive pressure gaseous oxygen from the cold box after the oxygen compressor pressurizes to a certain pressure for the user's use.

Faq of Medium sized separation plant

How does the air separation column and expander of high purity nitrogen unit work?

The air separation column mainly includes main heat exchanger, liquefier, distillation column, condensing evaporator, etc. The main heat exchanger, condensing evaporator and liquefier are plate type of heat exchangers. It is a new type of all aluminum metal composite partition heat exchanger. The average temperature difference is small, and the heat exchange efficiency is as high as 98-99%. Distillation column is the unit of air separation. The types of column unit are classified according to the internal parts. The sieve plate column with sieve plate, the bubble cap column with bubble cap plate, and the packed column with packing material. The sieve plate is widely used in air separation distillation column because of its simple structure, easy manufacture and high efficiency. Packed column is mainly used for distillation column with diameter less than 0.8m and height less than 7m. Bubble column is seldom used because of its complicated structure and difficult manufacture.
